Firstly, I own an Acer laptop originally having Windows 7, now upgraded to 8.1, & initially had 3 primary partitions (that is PQSERVICE, SYSTEM RESERVED & Acer (C:)). I decided to migrate my personal data to a dedicated partition, so I used the Disk Management utility to shrink some volume from Acer (C:). Then I made PQSERVICE & the newly created partitions logical whereas Acer (C:) & SYSTEM RESERVED were supposed to remain primary. This is how it appears in EaseUS Partition Master:
Pretty much like in MiniTool Partition Wizard:
However, that's not the case for the Disk Management tool as it considers both of them as logical:
Apparently, what the Windows Disk Management tool is displaying is more trustworthy as, whilst I'm trying to install Ubuntu onto the free unformatted partition, it doesn't seem to detect all the logical partitions & considers the whole drive as a single partition. It might as well have something to do with the MBR/GPT issue (I've got MBR if I'm not mistaken).
- Is it the problem which makes Ubuntu think there are no partitions on the drive?
- Either way, is it possible to fix that i.e. to make those partitions 'genuinely' primary, so that Windows Disk Management tool believe that?
